STOPPER OR CLOSING DEVICE FOR PREVENTING RECEPTACLES FROM BEING REFILLEEl.

SPECIFICATION forming part of Letters Patent No. 643,645, dated February 20, 1900. Application filed March 28, 1898. Serial No. 6 75,481. (No model.)

To all whom it may concern.-

Be it known that I, HENRI GUILLoU, a citizen of the Republic of France, residing at 208 Avenue du Maine, in the city of Paris, in the Republic of France, have invented certain new and useful Improvements in Stoppers or Closing Devices for Preventing Receptacles from Being Refilled; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved stopper or closing device arranged in the interior of the necks of bottles and other receptacles and serving to prevent such bottles or receptacles from being refilled with a liquid of any kind after having once been emptied.

This device is represented in various constructional forms in the accompanying drawings, in which Figure 1 is a vertical section of the said stopper or closing device applied to the interior of the widened neck of a bottle. Figs. 1 and 1 are an elevation and plan, respectively, of a clack-valve used in connection with the stopper. Fig. 2 shows in vertical section a slightly-modified construction of the stopper or closing device adapted to be applied to the interior of the large neck of a bottle, and Fig. 2 is a plan of the valve used therewith.

The stopper or closing device consists, first, of a hollow glass stopper b, provided with a diaphragm b partly blocking the lower part of its circular section, and, further, with acylindrical glass ring I), as seen in Fig. 1, or there may be two of such rings, as 1) b arranged adjacent to each other, as seen in Fig. 2, and each ring is provided with a diaphragm 19 which is preferably furnished with a flange b serving to prevent any rod or the like from being introduced into the clack-valve chamber. The stopper and ring or rings, as described, being of a uniform outer diameter, are united by a cement insoluble in water, and after having been thus cemented together they are ground into the neck a of the bottle a, Fig. 1, or into the compound neck q, Fig. 2. The stopperb is provided with a projecting flange d, Fig. 1, or with an annular piece (1, Fig. 2, which enables the stopperto rest upon the top edge of the neck, so that a free space is left between the bottom of ring 6 or ring (if the latter ring is used also) and the narrow part a of the bottle-neck a, Fig. 1, or the partly-blocked bottom end of the neck q, Fig. 2, which is sealed into the interior of the neck 03. The closing device comprises also a heavy clack-valve, of glass, porcelain, earthenware, or the like, provided with a long tailpiece c, with a truncated conical head 0, ground so as to fit the neck, and With a screw-threaded nipple c surmounting the head, this screw-threaded nipple affording means for holding the said clack-valve While being turned upon its seat 8 in order to simultaneously grind its head onto the said seat, and the device further comprises a spiral spring 1", either conical or cylindrical, which bears against the lower part of the screw-threaded nipple 0 being connected to the lower thread thereof,and extends in height over the whole chamber formed between the head of the clack-valve and the bottom face of the ring I) or W. The strength of the spring 1" is adjusted to the weight of the clack-valve, so that the spring yields under the weight of the valve when the receptacle is reversed, but so that it again returns the clack-valve to its seat when the receptacle is placed in an approximately horizontal position. I

When the bottle has been filled with the proper liquid, the clack-valve c, fitted with its spring 0", is inserted into its neck. After having covered the outer cylindrical part of the stopper and of its rings to be located in the interior of the neck with an adhesive material insoluble in water this stopper is inserted and slightly turned in its place, and thereupon the bottle is left alone for a few minutes until the adhesive substance is dry, whereupon the stoppering of the receptacle by ordinary means may be effected.

In order to empty the bottle, it is turned upside down. The clack-valve then recedes from its seat 8 and compresses the spring 7", while the liquid passes through the stopper and its rings. On returning the bottle to its normal position the clack-valve is returned to its seat first under the action of the spring and subsequently under that of its own Weight.

What I claim, and desire to secure by Letters Patent, is-

1. The combination with a bottle provided with an interior valve-seat in its neck, of a hollow stopper fixedly arranged within the bottle-neck, said stopperhaving a horizontal diaphragm partly closing the lower end of the stopper, a ring fixedly arranged below the stopper and having a horizontal diaphragm partly closing the lower end of said ring, said diaphragins projecting inwardly from opposite sides into position to prevent the insertion of an instrument through the ring, a valve arranged within the bottle-neck and adapted to normally rest upon the valve-seat therein, the parts being arranged whereby to leave an intervening space between the lower face of the ring and the valve, said valve having an upwardly-projecting screw-threaded stem or nipple, c and a spiral spring encircling the said nipple and bearing at opposite ends against the under side of the ring and the upper face of the valve, the said valve being of sufiicient weight to overcome the stress of the spring when the bottle is inverted, as and for the purpose set forth.

2. The combination with a bottle provided with an interior valve-seat in its neck, of a hollow stopper fixedly arranged within the bottle-neck, said stopperhaving a horizontal diaphragm partly closing the lower end of the stopper, a ring fixedly arranged below the stopper and having a horizontal diaphragm partly closing the lower end of said ring, a second ring arranged below the first ring and provided with a horizontal diaphragm partly closing its lower end, the various diaphragms projecting inwardly alternately from opposite sides whereby to provide a tortuous passage for the liquid and prevent the insertion of an instrument through the rings, an upwardlyprojecting flange at the edges of the diaphragins of the rings, avalve arranged within the bottle-neck and normally resting upon the seat therein, the parts being arranged whereby an intervening space is left between the lower face of the lower ring and the up per face of the valve, the said valve having an upwardly-projecting screw-threaded stem or nipple, and a spring encircling said nipple and bearing against the lower ring and the valve, said valve being of suflicient weight to overcome the stress of the spring when the bot tle is inverted, as and for the purpose set forth.

In testimony whereof I have aflixed my signature in presence of two witnesses.
